Drummond made the statements in a lawsuit he filed this week against the U.S. Anti-Doping Agency and Tyson Gay, the former sprint champion serving a one-year suspension for using a banned substance.

Drummond, a former Olympic sprinter, accuses USADA and Gay of defamation by suggesting that he encouraged Gay to use creams with banned substances or HGH. Drummond said he tried to throw out potentially banned supplements and accused Gay of lying to investigators to win a lighter suspension.

Gay returned the silver medal he won at the 2012 London Olympics after testing positive.
